I think i might have figured out the issue for my mpirun problem. I
setup a testbed 2 node cluster on 32bit p4's and everything worked. I
do the same steps on my 64bit system and it doesn't work.. I add the
master node of the 64bit system as a slave on my 32 bit system and this
happens <br>

that is without the 64bit system<br>
<br>
here it is with it<br>

mpich is compiled seperately on the 64bit system.. right now no nfs
mounts or sharing home directories.. this is all on centos 4.0
systems.. basic installs<br clear="all"><br>-- <br><a href="http://www.zcentric.com/wiki">http://www.zcentric.com/wiki</a><br>My Linux Howto/Tips Wiki
